I <br /> en viros® <br /> An Enviros geologist will supervise the drilling and describe encountered soils using the <br /> Unified Soil Classification System (USCS) Soil samples will be collected at five foot <br /> intervals and/or significant lithologic changes for lithologic description Soil sample <br /> intervals will be screened in the field for organic vapor by measuring head-space vapors <br /> using an organic vapor meter (OVM) <br /> Selected soil samples from each boring will be labeled, entered onto a cham-of-custody <br /> record, and preserved in a cooler with ice for transport to a State of California certified <br /> laboratory <br /> Ground water samples will be collected from each boring, labeled, entered onto a chain-of- <br /> custody record, and preserved in a cooler with ice for transport to a State of California <br /> certified laboratory <br /> An exploratory boring log will be prepared for each boring Head-space vapor <br /> measurements will be recorded on the log <br /> Task 5 Chemical Analysis <br /> Soil and ground water samples will be analyzed for TPPH according to EPA Method 8015 <br /> (modified), benzene, toluene, ethylbenzene, and xylenes (BTEX), methyl-tertiary-butyl- <br /> ether (MTBE) compounds according to EPA Method 8020, and oxygenates according to <br /> EPA Method 8260 <br /> . Task 6 Report Preparation <br /> Following the receipt of analytical results from the laboratory, Enviros will prepare a <br /> written report describing field procedures and presenting laboratory results, boring logs, <br /> and conclusions <br /> The scope of work described in this work plan will be performed under the supervision of <br /> a registered professional engineer <br /> Schedule <br /> Enviros is prepared to begin work upon approval of this work plan by SJCPHS and receipt <br /> of appropriate permits <br /> i <br /> 97373 3 <br />
